Electromagnetically shielding bonding film

摘要

Provided is bonding film in the form of web which has a high electromagnetic shielding effect for electromagnetic radiation from the front surface of a display device, and other favorable properties such as an infrared blocking property, a transparency, a invisibility and a favorable bonding property. The bonding film typically includes base film, a geometrically patterned electroconductive layer placed over the base film so as to achieve an aperture ratio of 80% or more, and a bonding layer for attaching the assembly to an object. The film may be applied to the surface of a transparent sheet member for the convenience of handling, and such an assembly has a symmetric structure so that the warping of the assembly may be minimized. The bonding film may be interposed between a pair transparent base sheets, or the bonding film may be applied over two sides a transparent base sheet. The assembly may further include an infrared blocking layer and an anti-glare layer.
